To all 'whom it may conce/m:

Be it known that L'CAssr'Us M. GAY, a

I citizenof the United States, residing at Los eles, in the county of Los Angeles, State alifornia, have invented certain new and useful Improvements in Gas-Engines, of which the following is a description, 'reference being hadv tothe accompanying drawing and to the figures of reference` marked thereon.

The invention relates to new and useful improvements in gas engines and more particularly to engines of this type wherein a rotary sleeve valve surrounding the c 11nder operates to control the intake an exhaust ports.

An objectof the invention is to provide a gas engine of the` above type with a central working barrel or cylinder in which the pistonreciprocatesE an rotary 'sleeve valve is located, which Working barrel or cylinder is supported at its'upper or explosive end and hangs Within said rotating sleeve valve.

A further object of the invention is to provide an engine of the above character with a water jacket. located in said working barrel, which water jacket substantially incloses the combustion chamber within the working barrel.

A further" object of the invention is to An of provide an engine of the above type wherein a plurality of working barrels are mounted in cylindrical housings castiintegral 'with' each other and closed by al common cover which serves to hold the-working barrels in place supported by the cylindrical housings.

.A still further object of ,the invention is to provide a device of theabove character wherein the cover is cast so as to form intakeA and outlet manifolds which are connected to 'lle vater' jaclret formed in each working arre still further object of the invention is to provide an engine of the above type wherein the working barrel is provided Ywith an intake'and an exhaust port inthe side walls thereof and wherein the rotating4 sleeve valve extends each side of 'said ports'end isv provided with an oil sealingchannel located each side of'said ports to prevent the escapo of the gases. I' v These and other objects will in part be obf vious andwill in part be hereinafter more fully disclo In vthe drawings winch snow by Nay of outside of iwhich the.

"will answer for theother.

illustration one embodiment of the inven-' tion, Figure 1 is a longitudinal vertical sectional view through anlengine embodying the improvements. Fig. `2 is a horizontal sectional view of the same. Figa 3 is a transverse `vertical sectional "view of the same. Fig. et.' is a view showing certain of the sleeve valves in side elevation and others in section and means for operating the same.

l The/invention consists, generally, in pro-v 'vldmg a gas engine which consists of a plu-v rality of cylinders, each of which has a working barrel formed with a water jacket extending throughout the greater length thereo and substantially surrounding the combustion chamber within said working barrel.v This working barrel is suspended at its upper 'or outer end fromthe cylinder housing and a rotary sleeve valve is disposed between said worln'ng barrel and said housing. A piston reciprocates in said working barrel and intake and exhaust ports are connected .with said working barre1.

The hhusings for the different cylinders are 'closed by a cover which is cast so as to provide an inlet and an outlet manifold which is connectedwith the water jacket in each working barrel. The sleeve valves for the diiferent cylinders are connected together so cent valvesrotate in reverse directions. Thesev valves*are rotated by a gear action with the main shaft. y l

'Referring more in detail to the drawings, the engine consists of a main supporting bed or casing 1 in which is journaled the main shaft 2 having the usual cranks formed therein.' `Mounted on this main casing, asherein shown, are four cylinders, each of which is Patented aug.' 24, 1915.

`as to rotate simultaneously, although adjav provided with a piston 3 connected-by a. pis f tonrod'4' to the respective cranks on the y main shaft. Each of thesecylinders are in the main similar and a description of one l `Each cylinder consists of an inner .working barrel 4 'which is formed .with a flange 5 at its upper or :outer end, which flange rests uponand is supportedby the cylinder housi'g 6.A l The cylinder housi, gs of. the different cylinders lare cast integral and, therefore, are provided with conireotin` webs 7. This workingulaarrel 4 is turne i 'c'y" der in which the piston reciprocates.

e upper end of the barrel is closed exce t for an opening extending therethrough, m

so es to form a truev which is inserted the spark plug S. The working barrel is also provided with a water space forming a water jacket for the combustion chamber. The space 9 extends entirely' about the sides ofthe working barrel within the range of reciprocation of the pistn and also extends over the top of the working barrel so that the combustion chamber in the working barrel is substantially the' other side of the cylinder.

surrounded by this water jacket. Said space is divided by suitable partitions l0 which terminate short of the bottom of the space so that the water for cooling may `be supplied at one sidelofthe cylinder. caused to circulate about the same. and pass out from Each working barrel is provided with an intake port- 11 and anexhaust port 12. These ports are formed in the side walls of the working barrel.

Located between" the working barreland the cylinder housing is a sleeve valve 13 which extends above the intake and exhaust ports. Said valve sleeve and cylinder housing are provided'with oil grooves 14 and 15 which are disposed above and below the intake and exhaust ports to 'prevent escape of the gases. The valve sleeve is provided with al single port 16 which is so disposed s'to register with irst the intake port and then the exhaust port as the sleeve rotates.

vThe sleeve valve at its lower end is provided with a gear 17 which may be attached thereto in any suitable way. The gears of the sleeves of the adjacent cylinders intermeshand the rotating sleeve valve of the first. cylinder is also provided with a beveled gear 18 which meshes with a beveled gear 19 on an intermediate shaft '2O and this beveled gear 19 is formed with a separate gear meshing in turn with a gear 21 splined to the main shaft. As the main shaft rotates, .each of the sleeves will be rotated and these gears are so proportioned that the sleev: rotates once for each two complete rotations of the main shaft.

"Each rotating sleeve isr formed with an annular projecting rib 2'2 and a grid ring Q3 is 'held 'between the gear fastened to the sleeve and this annular rib.

The cylinder housings 'are closed at their upper ends' b v a cover 24. clearly shown in Fig. 3, is cast so iis to form an intake water manifold 25 and an exhaust water manifold Q6. The intake manifold is connected to one side ot the waterjacket and the exhaust mani told is connected Awith the' other side of the'water jacket. This cover is bolted to the cylinder housings by. suitable bolts QT and the cylinder housings are in .turn bolted to the bed castings by bolts QS. The intake ports of the cylinders on opposite sides of the center of the engine are adjacent to each other and are connected to an intake manifold 29. The ex- This cover 24, as

said worln'ngbarrel 1s suspended nected to an exhaust manifold 30.

Iny order to disassemble the parts, the.

cover is removed, Awhich exposes the upper end of each of the cylinders. The working barrel in each cylinder may be then removed as it is suspended or supportedby the cylinder vhousing at the outer or explosive end of the cylinder. The c'vlinder housings may also be readily remove by taking out the bolts which secure the same gine. This exposes the sleeve valves which may also be removed, if desired, by taking out the supportinggrid rings.'

From the above description it will be apparent' that I have provided a multiple gas engine'in which each cylinder is provided with a working barrel which incloses andl forms the explosive chamber and this explosive chamber is substantially surrounded by a water jacket which prevents the excessive heating of the lubricant used inconnectiou with the rotary sleeve valve. Not only have I provided an vengine which is. very efficient in action but also one which is very simple in construction and can be cheaply made and readily assembled or disassembled when desired. It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus described my invention, what I claim is:
